HAMDEN, Conn. — Two Longmeadow residents died Wednesday afternoon following an accident on the Wilbur Cross Parkway in Connecticut.

Connecticut State Police reported that just before 4 p.m., a white van occupied by the western Massachusetts residents struck the guard rail on Route 15 near exit 60 and rolled over.

The driver, 22-year-old Firas Oadeh and passenger, 42-year-old Timothy Fagan, both reportedly from Longmeadow, were ejected from the vehicle and killed, police say.

According to a report by WFSB.com, one of the men was sent flying into the oncoming lane where he was struck by another vehicle, and ultimately killed. The driver of that vehicle was uninjured, police said.

Both victims were pronounced dead at the scene. The van, owned by Advanced Caulking and Restoration LLC. out of Hartford, was destroyed, police said.

Traffic was backed up for several hours and miles on Wednesday as state police worked to determine what caused the crash. The state's accident reconstruction team remained on the highway for much of the night, finally clearing the area shortly before daybreak.

No cause has been determined and the investigation is ongoing as of Thursday morning.

As news of the victims' deaths spread, friends of Oadeh began writing on his Facebook page. Oadeh, who listed himself as a New York City native currently living in Springfield, would have turned 23 on Christmas, according to his profile.

Fagan's Facebook profile was set to semi-private, disallowing anyone not directly connected with him to view his complete profile.
